@robwalker -
Several years ago, a friend of 40 years wanted to walk the
Camino Frances. He had, however, been diagnosed with Frontotemporal Dementia a handful of years earlier. He had actually been featured in an article in Forbes about the disease a couple years before.
His wife, knowing that I had walked, asked me how his wishes could be fulfilled...basically the question that you ask in the OP. Hmmmmm...
After some back-and-forth with his doctors, she gave me a list of potential problem situations and what parts of daily life/routine did not pose a problem at all. That empowered me to suggest myself as a guide. For both my friend and I, it turned out to be one of the most important events in our lives. So, my advice is simply, "Fear not!"
For relevant (maybe) background, my Camigo had three major needs of me: 1) His diminished executive function put me in charge of timely "getting out of town" in the morning and the "keeper of routine" upon arrival in the afternoon/evening. 2) For the same reason as above, I was totally in charge of his mix of medications on a daily basis. 3) His fine motor skills were slightly impacted and impacted both his gait and ability to listen to his body...so I provided a lot of first aid on his feet between SJPP and Moratinos.
PLEASE feel free to PM me (via the envelope icon just right of your sign-in avatar and look there to start a new conversation) if you wish to share concerns, pre-trip logistics, etc. The topic might tend to a more intimate conversation than you wish to have in a public forum.
I may not come back to you immediately but your post now has my full attention and I will look for any response as time permits.
